Fingerprint Licensing

Zero-knowledge licensing - we only store certificate fingerprints, never your actual keys

Privacy by Design

Our licensing system is built on a fundamental privacy principle: we never see, store, or have access to your actual certificates or private keys. We only work with SHA256 fingerprints - cryptographic hashes that uniquely identify your certificates without revealing their contents.

This zero-knowledge approach means your PKI remains completely private, even from us.

How It Works

  • ✓ Your CA generates a fingerprint locally
  • ✓ Only the fingerprint is submitted for licensing
  • ✓ We never receive your actual certificate
  • ✓ License verification happens locally
  • ✓ Complete privacy for your PKI
